ABC.com runs an Oracle 11g database. Over time they begin to complain about nightly write
issues. After a complete review, no issues were found on the server.
What is the most probable cause?

ABC.com owns a CX3-40 SAN for their Microsoft application environment. In the course of a
SnapView implementation, you discover that the Microsoft file systems are misaligned on the
production LUNs. The file systems need to be aligned prior to implementing SnapView for these
hosts. Host downtime needs to be kept to a minimum.

What is the best method to achieve the desired objectives?

ABC.com has recently added four Symmetrix arrays and six CLARiiON arrays to the SAN
environment. EMC ControlCenter allocation tasks for the Symmetrix storage now run significantly
slower. Production server access to the Symmetrix and CLARiiON arrays has not changed. What
is a likely cause of the problem?

A customer has decided to consolidate storage onto a CLARiiON. There is a mix of Windows and
UNIX workstations in the environment. One goal is to use point-in-time copies of data to make
backups easier. A secondary goal is to use the point-in-time copies to perform a fast recovery in
the event of data corruption.
Your initial survey of their environment shows that the read/write ratio of their application is 1:1.
The application appears to be sensitive to disk response times, especially when updating

engineering design documents.
Which initial solution should you consider?

ABC.com wishes to share storage on a Symmetrix between hosts belonging to the Sales and
Engineering departments. Each department should be allowed control over their devices while
being denied the right to control the other department’s devices. Neither department should be
allowed to make changes to device masking.
Which solution should the customer select?

A Rainfinity administrator is interested in protecting data in the event of an outage. Currently there
are two sites approximately 100 miles (160.93 kilometers) apart. Which configuration option offers
the highest level of protection for the administrator?

A customer is deploying a Microsoft Exchange 2003 environment and has requested assistance
with the associated disk design. They are deploying Exchange for 850 users with an average of 3
I/Os per user. They expect a 60% read and 40% write distribution.
The customer would like to know the number of disks required for both RAID 5 and RAID 1/0 DMX
configurations with 10k rpm drives.
How many disks are required for each configuration type?

ABC.com wants to implement one EMC Disk Library at their primary data center and one EMC
Disk Library at their disaster recovery site with IBM Tivoli Storage Manager (TSM) as the backup
application. A small subset of the primary data needs to be transferred to a disaster recovery site
where it will eventually expire without TSM involvement.
What is a recommended feature to use with EMC Disk Library to transfer data to the disaster
recovery site?

ABC.com plans to locate their primary production site and their secondary disaster recovery site
1,000 kilometers apart. The EMC account team has recommended they use DMX-3s running
SRDF/A. During the planning phase it is estimated that: The SRDF/A minimum cycle time
parameter will be set to 20 seconds It will take 3 hours after a primary site failure to declare a
disaster and failover to the secondary site
After a failover to the disaster site, it will take two hours to bring up the applications and make the
secondary site operational
What is the minimum recovery time objective that this supports?

What is the maximum number of log sets that need to be accounted for in designing a storage
solution for Microsoft Exchange Server 2007 Enterprise Edition?
